Abstract
Damage to deck & purposeful penetrations have much in common - the location & severity are seldom known beforehand. Usually the designer knows the general area where a vent stack may cut the roof, or approximately where a telephone conduit may pierce the slab; and he may not know how big the hole will be. This lack of info makes it hard to advise how a hole should be reinforced - it at all - or how damaged deck should be repaired. Guide specs reflect this lack of specific knowledge; the Steel DEck Institute states, "Openings not shown on the erection diagram,s such as those required for stacks, conduits, plumbing, vents, etc., shall be cut ( and reinforced, if necessary) by the trades requiring the openings." The designer should certainly be consulted for reinforcing requirements, but frequenlty, unless details are shown on the plans, no reinforcing is provided and the designer is not consulted.
